Technical Field

[0001] The utility model relates to the technical field of diaphragm coating scrapers, in particular to a carbon fiber scraper with a replaceable scraper. Background Art

[0002] Coating refers to the process of applying polymer paste, polymer liquid or molten polymer to composite materials such as paper, film, cloth, etc. It is widely used and mainly applied to substrates such as paper and film. There is also a process of diaphragm coating in lithium battery production. Lithium battery diaphragm coating film refers to a process material that coats the coating on the surface of lithium battery diaphragm. When applying, a carbon fiber scraper is often used to apply it, so that the application is more uniform.

[0003] However, some carbon fiber scrapers and blade holders are integrated. When the scraper on the equipment needs to be replaced, the blade holder needs to be removed together. The blade holder of many carbon fiber scrapers is cumbersome to disassemble, which makes the disassembly and installation efficiency slow. Moreover, when replacing a new carbon fiber scraper, only the entire blade can be replaced, and the blade holder needs to be replaced together, which results in high cost loss. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-7 A carbon fiber scraper with a replaceable scraper comprises a carbon fiber scraper blade 1, the carbon fiber scraper blade 1 is mounted on a blade holder 2, a pressing plate 3 is movably mounted on the upper end of the blade holder 2, and a fixing bolt 4 is mounted on one side of the middle of the pressing plate 3;

[0024] Springs 7 are provided on the lower surfaces of the two side ends of the pressing plate 3, a plurality of limit blocks 31 are evenly arranged and fixed on the bottom surface of the pressing plate 3, a mounting plate 32 is connected to one side of the middle part of the pressing plate 3, and a protrusion 33 is fixedly connected to the middle part of the upper surface of the pressing plate 3.

[0025] Among them, a second rubber pad 6 is attached to the bottom surface of the pressing plate 3, a through hole is opened on the mounting plate 32, and the fixing bolt 4 can pass through the through hole on the mounting plate 32. After the fixing bolt 4 is screwed into the bolt hole 23, the pressing plate 3 can be pressed, thereby preventing the pressing plate 3 from being separated from the mounting cavity 21.

[0026] In addition, a mounting cavity 21 is provided on the knife seat 2, and the carbon fiber scraper blade 1 is horizontally inserted in the mounting cavity 21. A bolt hole 23 is provided on one side of the middle of the upper surface of the knife seat 2, and the fixing bolt 4 can be screwed into the bolt hole 23, and the bolt hole 23 is centrally aligned with the through hole of the mounting plate 32. Mounting heads 22 are connected to both sides of the knife seat 2, and the mounting heads 22 are used to install fixing components so that the carbon fiber scraper is installed and fixed as a whole to the equipment coating equipment.

[0027] In addition, a first rubber pad is attached to the bottom wall of the installation cavity 21, a positioning block 25 is symmetrically arranged on one side of the bottom wall of the installation cavity 21, and a movable cavity 24 is symmetrically connected to the side walls on both sides of the installation cavity 21. The positioning block 25 is convenient for effectively positioning the position of the carbon fiber scraper blade 1 after it is inserted into the installation cavity 21, thereby ensuring that the upper limit block 31 can be effectively pressed into the limit opening 12.

[0028] Moreover, the other end of the spring 7 fixed on the bottom wall of the movable cavity 24 is away from the pressing plate 3, and the pressing plate 3 moves up and down in the installation cavity 21 and the movable cavities 24 on both sides. Under the connection of the springs 7 on both sides and their elastic contraction, the pressing plate 3 can quickly press the carbon fiber scraper blade 1 after the carbon fiber scraper blade 1 is inserted, and under the contraction of the spring 7 and after the fixing bolts 4 are installed, the carbon fiber scraper blade 1 is difficult to fall out.

[0029] In addition, a positioning opening 11 corresponding to the position of the positioning block 25 and having the same shape as the positioning block 25 is symmetrically opened on the side wall of one side of the carbon fiber scraper blade 1. A plurality of limit openings 12 are opened through the carbon fiber scraper blade 1, and the position of the limit opening 12 corresponds to the position of the limit block 31 above, and the hole type of the limit opening 12 is consistent with the shape of the limit block 31. The limit opening 12 facilitates the buckling of the limit block 31, thereby preventing the carbon fiber scraper blade 1 from being separated from the mounting cavity 21.

[0030] In this embodiment, when using lithium battery diaphragm coating, it is necessary to install the carbon fiber scraper on the coating equipment. First, the knife seat 2 is installed on the equipment through the installation heads 22 and fixing parts on both sides, and then the carbon fiber scraper blade 1 is used for scraping during operation. Once the carbon fiber scraper blade 1 needs to be replaced, the operator does not need to disassemble the knife seat 2, but only needs to unscrew the fixing bolt 4 first, and then pinch the protrusion 33 with his hand to lift the pressing plate 3. At this time, the pressing plate 3 slowly separates from the pressed carbon fiber scraper blade 1, and the spring 7 is stretched and deformed. Once the limit block 31 is completely pulled out from the limit opening 12, the carbon fiber scraper blade 1 can be pulled out from the installation cavity 21.

[0031] After removing the old carbon fiber scraper blade 1, the new carbon fiber scraper blade 1 can be inserted into the installation cavity 21, with the side of the positioning port 11 facing the installation cavity 21, and then inserted. After ensuring that all the positioning ports 11 and the positioning blocks 25 are in contact, the hand that was originally pinching the protrusion 33 can be released. In the absence of external force, the spring 7 contracts and pulls the pressing plate 3 into the installation cavity 21, thereby pressing the carbon fiber scraper blade 1. At the same time, the limit block 31 is completely inserted into the limit port 12, thereby playing a limiting role to prevent the carbon fiber scraper blade 1 from falling out of the installation cavity 21. Then the fixing bolt 4 can be re-passed through the through hole of the mounting plate 32 and screwed into the bolt hole 23 to ensure that the pressing plate 3 will not detach.

[0032] Under the contraction of the spring 7, the pressing plate 3 can effectively press the carbon fiber scraper blade 1 to play a certain pressing role, preventing the carbon fiber scraper blade 1 from falling off, and cooperate with the fixing bolt 4 to make the pressing and fixing more firmly, and the first rubber pad 5 and the second rubber pad 6 can effectively fit the carbon fiber scraper blade 1 during pressing, preventing the carbon fiber scraper blade 1 from breaking due to over-tight pressing.

[0033] In the utility model, a movable pressing plate 3 is arranged on the knife seat 2, so that when the carbon fiber scraper is replaced, a new carbon fiber scraper blade 1 can be replaced without disassembling the knife seat 2. The pressing plate 3 can effectively press the carbon fiber scraper blade 1 to play a certain pressing effect, and cooperate with the fixing bolt 4 to make the pressing and fixing more firmly, so that the carbon fiber scraper can be directly replaced without disassembling the knife seat 2, thereby effectively reducing cost loss, and there is no need to prepare more carbon fiber scrapers with knife seats 2, only the carbon fiber scraper blade 1 needs to be prepared, and the disassembly and installation method is also convenient and efficient.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
